LIQUID-RECEPTAGLE.

1,os2,ec1.

To all whom it may concern Be it known that 1, WILLIAM H. TUCKER, acitizen of the United States, residing at EoXbury, Boston, in the countyof Suffolk and State of Massachusetts, have invented new and usefulImprovements in Liquid- Receptacles, of which the following is aspecification.

This invention relates to useful improvements in liquid receptacles.

The object of the invention is to provide a receptacle having a siphonattached thereto by which liquid contained in said receptacle may beremoved therefrom in large or small quantities as desired, withouthaving to tip the receptacle.

The invention consists in the combination and arrangement of partswhereby the above object and certain other objects hereinafter appearingare attained, as set forth in the following specification andparticularly pointed out in the claims.

Referring to the drawings: Figure 1 is a sectional elevation of a deviceembodying my invention. Fig; 2 is a detail sectional view taken on theline 22 of Fig. 1. Fig. 3 is a detail section partly in elevation takenon the line 33 of Fig. 2.

Like numerals refer to like. parts throughout the several views of thedrawings.

In the drawings, 5 is a receptacle, which although it may be constructedin any desired form, is preferably provided with an opening at the topand a cover 6 adapted to close said opening and with a handle 7pivotally attached to said receptacle by which the same may be morereadily moved from place to place.

, The receptacle 5 comprises a main reservoir 8 and a supply chamber 9preferably cylindrical in shape and vertically arranged relatively tothe main reservoir, said supply chamber and said main reservoir beingconnected by an opening 10 at the bottom of the dividing partition.

An inverted U-shaped siphon tube 11 is arranged in connection with thesupply chamber 9 with the leg 12 thereof telescop ing said chamber. Avalve seat 13 is formed adjacent to the extremity of the leg 12 and isadapted to be engaged by a valve 141 having yielding engagementtherewith and being normally retained in said engagementby a spring 15encircling the stem 16 of said valve, said stem having slidingengagement with a support 17 which is secured to said Specification ofLetters Patent.

leg 12. By reciprocating the leg 12 of the siphon 11 longitudinally ofthe supply chamber 9 said valve is arranged to be opened or closedaccording to the direction of movement of said leg and as said valve isopened the liquid contained within the main reservoir 8 will be siphonedoutwardly through the opening 10 and discharged at the free end 18 ofsaid siphon tube.

In order that a reciprocatory movement may be imparted to the valve 14to open the same during the telescopic movement of the leg 12 within thechamber 9 I preferably provide a pair of levers 19 pivoted at 20 to thesupport 17 which in turn is secured to the extremity of the leg 12 bymeans of a screw-threaded collar 21. A sleeve 22 is adapted to encirclethe support 17 and is provided with slots 23 which receive the ends 24:of the levers 19. The support 17 constitutes a guide for the sleeve 22and during the telescopic movement of the leg 12 downwardly within thechamber 9 the sleeve 22, which engages the bottom of said chamber,continues to remain static-nary while the support 21 is moved downwardly thereby and consequently the levers 19 by engaging the ends ofthe slots 23 will be rocked upon their pivots 20. The inner ends of saidlevers 19 are arranged within a transverse slot 25 in the stem 16 of thevalve 14 and engage a pin 26 therein, consequently as said levers 19 arerocked, as hereinbefore stated, the stem 16 will be moved thereby andthe valve 14 moved from the valve seat 13 to quite a considerabledistance therefrom, owing to the increased leverage of the levers 19. Itwill be obvious that as said valve is opened the liquid encircling thevalve stem and the means for operating said valve will be admitted intothe tube 11, it being understood that the level of the liquid within thereservoir 8 is higher than the uppermost point in the interior of thetube 11.

The action of a siphon tube is so well known to those skilled in the artthat a full description of the same is not thought to be necessary,suflice it to say that after said tube has been once filled and all ofthe air ejected therefrom, the closing of the valve 1 1 will retainliquid enough in said tube to completely fill the same and when the legsof the U-shaped tube are of a sufficient length in proportion to theirdiameter, said liquid will remain therein with the free end of the tubeopen, for an indefinite period. In the present embodiment of theinvention it is desired that the diameter of the tube constituting saidsiphon should be quite large and as the leg of said siphon tube has beenpurposely shortened to permit receptacles to be placed upon the supporton which the receptacle 5 is resting, beneath the end 18 the liquidcontained within said tube would be permitted to flow therefrom in casesaid receptacle is set down suddenly so as to cause a jar. To preventsuch an oc currence a screen, preferably consisting of wire gauze 27 offine mesh, is placed against the end 18 of the siphon tube 11 and ascrew-cap 28 having an opening 29 therethrough is placed upon the end ofsaid tube, said screen also serving as a filter as well as a support forthe liquid contained in said tube and retards the admission of airthereinto thereby maintaining the column of liquid.

As hereinbefore described, the leg 12 of the siphon tube 11 is adaptedto be reciprocated within the supply chamber 9 and as said supplychamber terminates slightly below the high water mark within said mainreservoir 8 I have provided a cap 30 having screw-threaded engagementwith the upper end of said cylindrical tube, which constitutes a packingto prevent said liquid contained within said receptacle from overflowingthe top of the supply chamber 9.

The collar 21 which is secured to the eX- tremity of the leg 12 andcomprises the seat 13, and the support 17 for the levers 19, is slightlyenlarged at 31 to fit the interior of the cylindrical tube 9 and alsoassists in preventing the overflow of the liquid from said supplychamber.

A handle 33 is provided on the siphon tube 11 by which said tube may bereciprocated to operate the valve 14. By reference to Fig. 1 it will benoticed that the valve 14 is located at a substantial distance from thebottom 34 of the receptacle, but slightly below the end 18 of the siphontube 11, this position of said valve being necessary in order to provideroom for the mechanism beneath said valve to operate the same when saidsiphon tube is reciprocated, This height of the valve prevents thedrawing off of the entire amount of liquid contained within saidreceptacle, it being a well known fact that the liquid will ceaseflowing through a siphon when the level of the same within thereceptacle from which the liquid is being withdrawn, reaches the levelof the discharge end of said siphon. By extending the end of the leg 12,within the supply chamber 9, slightly below the end 18 of said siphonthe liquid, as above stated, will cease flowing before it has arrived ona level with said end and there will consequently be a suficientquantity of liquid to support the column of liquid within said siphonwhen the valve 14 is opened, to prevent the same from running back intosaid main reservoir.

lVith a receptacle constructed after the pattern of that illustrated inthe drawings, too much liquid would remain in the bottom thereofparticularly when it is desired to heat but a small amount of the liquidat a time, therefore an air tight draun 35 has been secured adjacent tothe bottom of said main reservoir 8, said drum being of a sufli cientdepth to displace the greater portion of the liquid which wouldordinarily be contained therein, the lower wall 36 of said drum beingarranged a slight distance above the bottom 34 of the receptacle.Several passages 37 are provided around the periphery of said drum 35and a passage 38 is also provided extending substantially through thecenter of said drum, all of said passages uniting the chamber 39 belowsaid drum with the rest of the main reservoir 8 and as the liquid, whichis contained within said chamber 39 is heated the same will circulateupwardly through the passages 37 and 3S and the cold liquid at the topwill settle to the bottom beneath said drum.

The general operation of the device hereinbefore specifically describedis as follows: The main reservoir 8 is filled with liquid to the heightas indicated in Fig. 1, which is preferably slightly above the uppermostpoint upon the interior of the U-shaped siphon tube 11. The receptacleto be filled with liquid from the main reservoir 8 is placed beneath theend 18 of said siphon tube and by placing the hand against the handle 33said tube will be depressed, whereupon the levers 19, carried by thesupport 17 which in turn is supported upon the end of the leg 12 of saidsiphon tube, will engage the ends of the slots 23 in the sleeve 22 andbe rocked upon the pivots 20, engaging the pin 6 in the valve stem 16causing said valve 14 to move away from its valve seat 13 and permittingthe liquid from the main reservoir 8 to fill the tube 11 completelydischarging the air therefrom. After suflicient liquid has beenwithdrawn from the receptacle 8 the hand is removed from the handle 32and the spring 15 returns said tube to its normal position and the valve14 in contact with its seat 13. As soon as the pressure is removed fromthe column of liquid within the tube 11 the same will cease to flow fromthe end 18 and said tube will remain filled with the liquid until thenext draft from the main reservoir is desired. Should the liquid withinsaid siphon tube for any reason become discharged from the same and thelevel of the liquid in the main reservoir be below the uppermost pointthereof, it will be impossible to again start the flow of liquid fromthe tube 11 without first removing said tube from the supply chamber 9inverting the same, opening the valve 14 and filling the tube withliquid, then closing the valve after which said tube may be inverted andreplaced in its position. As will be seen in Fig. 1, the leg 12 of saidsiphon tube is, in addition to being slidably arranged within thechamber 9, also rotatably arranged therewithin and consequently when thedevice is not in use the free end 18 may be swung back against the sideof the receptacle 5 thus taking up less room.

Having thus specifically described my in vention, what I claim anddesire by Letters Patent to secure is:
